What ST20000NM007D is

Seagate Exos drives are built for data-centre duty: 24/7 operation in servers, storage arrays, backup targets and large NAS systems, with a 2.5 million hour MTBF, a 550 TB/year workload rating and a 5-year limited warranty. The Exos X20 is a helium-sealed 7,200 RPM CMR drive, so it behaves properly in RAID and ZFS pools rather than slowing to a crawl on rebuilds the way shingled (SMR) drives can.

This listing is for the Seagate Exos X20 20TB Enterprise HDD 3.5" SATA 6Gb/s 7200RPM, manufacturer part number ST20000NM007D, supplied brand new and sealed with Seagate's 5-year limited warranty. It is the standard SATA model; if your array needs SAS or self-encrypting (SED) drives, tell us and we will quote the matching part number instead.

What to check before you order

SATA, not SAS

ST20000NM007D is SATA 6Gb/s. It runs on SATA controllers and on most SAS backplanes, but it is single-port. If your storage uses dual-path SAS, you need the SAS version of this drive.

Controller and backplane support

Older RAID controllers, NAS units and drive bays may not recognise 20 TB-class drives. Send us the server or NAS model and we will check before you order.

Drive trays and carriers

Servers from Dell, HPE and Lenovo need the correct drive carrier for each bay. Tell us the server model if you need trays supplied with the drives.

512e or 4Kn

The drive ships as 512e, which every current OS and controller accepts. It can be switched to 4Kn with Seagate FastFormat if your platform prefers native 4K sectors.

Rebuild time at this capacity

A 20 TB drive takes many hours to rebuild. For arrays of large drives, RAID 6 or an equivalent dual-parity layout is the safer choice, and so is keeping a spare on hand.

Buying Seagate hardware in the UAE

We supply against your company LPO and issue a VAT tax invoice under TRN 105539797800003. Delivery is same or next working day in Dubai and two to three working days across the rest of the UAE. For quantities, send the total rather than asking per unit — on memory, storage and GPUs the price moves with volume more than with anything else.

If you are not certain this is the right part, tell us the machine it is going into — server model, workstation, NAS or storage array — and we will confirm compatibility before quoting rather than after delivery. We would rather lose a line item than send you something that does not fit.

Questions about ST20000NM007D

Is ST20000NM007D CMR or SMR?

ST20000NM007D is a CMR drive, so it is suitable for RAID, ZFS and other arrays where SMR drives cause slow rebuilds.

Is ST20000NM007D SATA or SAS?

ST20000NM007D is the SATA 6Gb/s model. Seagate makes SAS 12Gb/s versions of the Exos X20 under different part numbers, and we can quote those if your system needs SAS.

Will this work in our server or NAS?

In most cases, yes. ST20000NM007D is a standard 3.5-inch SATA drive. Send us the server, storage or NAS model and we will confirm support, the drive tray you need and the bay count before quoting.

Is it new with warranty?

Yes. ST20000NM007D is supplied brand new and sealed, with Seagate's 5-year limited warranty.

Do you have ST20000NM007D in stock in Dubai?

Yes - ST20000NM007D is held as ready stock. Send the quantity you need and we confirm availability and price the same working day, with delivery same or next working day in Dubai and two to three days across the rest of the UAE.

Why is the price not shown on the page?

Enterprise memory and NAND pricing moves daily. Publishing a number that is wrong by the time you read it helps nobody, so we quote against your actual quantity and delivery date - usually within the same working day.

Do you supply against a company LPO with a VAT invoice?

Yes. We supply against your company LPO and issue a VAT tax invoice, TRN 105539797800003. Delivery is same or next working day in Dubai and two to three working days across the rest of the UAE.
